Fencing on unlevel ground

Our fencing is able to be put up on unlevel ground. Depending on how much on an incline or decline there are a few options. If the change is dramatic then the best ting to do is step the fence so that it drops down with the incline. If the change is not dramatic then the best thing to do is instal the fence as you normally would and allow the fence to follow the contour of the ground.
